Hi Forum

Can someone help?

There's a question that states

$\displaystyle 1+\log_{n!} {(n+1)} = \log_{n!} {(n+1)!}$

But how was this thought?

Where could I find about this identity on the web?

The question is actually

$\displaystyle \displaystyle\prod_{n=2}^{10} (1+\log_{n!} {(n+1)}) $

Does it change anything by being Cartesian product?

Thanks
